Couldn't a moving vehicle doppler shift the phase enough to cause multipath distortion or even to cause signal strength to vary with the beat frequency between it and other reflected or stationary signals? There may also be reflected signals shifted both up (forward to travel) and down (aft of travel). ----- Original Message ----- From: "Daniel Taylor" <dante+tcwug at plethora.net> To: <tcwug-list at tcwug.org> Sent: Tuesday, July 23, 2002 9:50 AM Subject: Re: [TCWUG] Doppler on what? > On Tue, 23 Jul 2002, Chuck Cole wrote: > > > Existence of a voice level doppler shift in a supposedly digital scheme like > > GSM is hard to accept... > > > I think he is referring to doppler on the RF signal possibly causing a > loss of the signal.
